Exhaust ring for manufacturing semiconductors



FIG. 1 is a front/top perspective view of an exhaust ring for manufacturing semiconductors showing my new design;

FIG. 2 is a top plan view thereof, the bottom plan view being a mirror image and, therefore, not shown;

FIG. 3 is a front elevational view thereof, the left-side elevational view being a mirror image and, therefore, not shown;

FIG. 4 is a right-side elevational view thereof;

FIG. 5 is a rear elevational view thereof;

FIG. 6 is a reference front elevational view thereof;

FIG. 7 is a right-side cross-sectional view taken along line 7—7 in FIG. 6; and,

FIG. 8 is an enlarged, partial, cross-sectional view taken along line 8—8 in FIG. 7.

The exhaust ring for manufacturing semiconductors is used in a vacuum vessel for manufacturing semiconductors. 

I claim the ornamental design for exhaust ring for manufacturing semiconductors, as shown and described.
